Blind Flanges Size Standards Pressure Ratings and Exporter and Supplier in India

Metallica Forging Inc. which is recognized for its engineering brilliance and reliability is a typical example of a blind flange manufacturer who offers precision-engineered flange ends made from stainless steel, carbon steel, and top-grade alloys. These devices are the most efficient in sealing pipe ends in cases of system shutdowns, pressure testing as well as maintenance since they are the ones that are designed to have no central bore. Their extraordinary strength and the ability to tight sealing render them the most important component to be found in refineries, power plants, and marine applications. The selection of a particular type of flange i.e. raised face, flat face, or RTJ is aimed at satisfying the industrial standards for performance.


These blind flanges are designed to be compatible with worldwide quality and size standards and, as such, they guarantee long service life and high dependability even in challenging environments. To ensure that they can work efficiently and maintain their mechanical strength, our flanges are put through a variety of tests. Through the B2B solution that we offer and which is very efficient, reliable, and convenient, clients can easily obtain the exact specification of Industrial Flanges that they need. Every single purchase may be altered in terms of size, thickness, and pressure rating and this is made possible by a well-functioning logistics system that is capable of providing rapid delivery and safe packaging for the projects that are of great importance in the industrial ​‍​‌‍​‍‌​‍​‌‍​‍‌sector.

Blind flanges are used to permanently or temporarily close the end of a piping system, allowing safe pressure testing and future line expansion. Material and pressure class selection directly affect load capacity and sealing reliability under operating conditions. Facing type plays a key role in gasket performance and leak prevention. During layout planning, Slip on Flange options are sometimes compared for sections where easy alignment and frequent dismantling are required. On a B2b Platform, detailed tables like this enable accurate evaluation of sizes, ratings, and materials before procurement.
